Performance impact when Pega application server migrate from Java 7 to Java 8.
I've an application running on Pega 7.2 version on weblogic server with java 7 version. I need to upgrade Java version from 7 to 8. I would like to understand performance impact/change after upgrade.
Have few questions:
- Is there any possibility of performance change (increase/decrease) after upgrade?
- Is there any recommendation on change in JVM argument or any other settings?
Please provide inputs if someone have experience or performed similar exercise. Thanks.

Hello Akshay,
Adding to Pawan's response, from a Pega perspective, it's unlikely that there will be much difference in terms of performance. You can check the below link in order to get an idea how normal applications perform when migrated to Java 8.

Also, if you have TLS related integrations, you would have to keep in mind that Java 8 uses TLS 1.2 protocol by default.
Thank you,

Hello Akshay,
Platform support guides discuss few Notes on Java Virtual Machines and Known Issues with JVMs.
Moreover, you can refer the release notes and deployment guides on PDN for Pega 7.2 to get more insights around this.
Other PSC members should be able to add to their insights to my response.
Sincerely,
Pawan
